, VENTIL'ATORL 7' Specification of Letters Patent; Y Patented Dec. 26,1906.

Application filed June 30, 1906. Serial No. 324.239.-

To all whom it may concern.-

Be it'known that I, MILES TOWNSEND, a citizen of the United States,residing at Marshall, in the county of Calhoun and State of Michigan,have invented a new and-useful Ventilator, of which the following is aspecification.

This invention relates to ventilators for buildings and .otherstructures.

The object of the invention is to provide a strong, simple, durable, andinexpensive ventilator which is adapted-to be applied to buildingshaving walls of different thickness and by means of which the structurescan be without'permitting the entrance of'rain,

' the following claims without departing from the spirit of theinvention or sacrificing any ofits adv ntages.

In the accompanying part of this specification, Figure 1 is averti= calsection through a wall equippedwith one 1 of the ventilators of thisinvention," Fi 2 is a front view of a ventilator. Fig.3 1s a rear view.Fig. 4fis a detailedsectional view:-

\ The improved ventilator of this inventibn preferably co'nsistsfof anouter member A and an inner member B. The inner member Bpreferably istelescopically fitted into the .rear end of the o'uterm'ember A, so thatit can be suitably adjusted therein tofit Walls' Each of the members ofdifferent thickness. A and B preferably is parallelogrammatic incross-section, as shown, so that when the front 'a-nd'rear ed 'esthereof are in-vertical position, so a's-to e in parallelism with thewall or support 0, the tops and bottoms of the members A and B will beupwardly and rearwardly inclined with respect to the front face ofthe'wall' or support C.

I The outer member A, which preferably is drawings, forming vconstructed of sheet metal, is rovided at the front edges of its top 1wit a depending storm-flange 2 and at the front ed e of its bottom 3withra, depending storm-t lange 4. At'the forward edges of its sides 5the outer member A is formed with oppositely and laterally extendingstorm-flanges 6. As shown in the drawings, the inner and outer ends ofthe member A are open. Extendin from side to side of the member A in ahorizontal direction is a plurality of storm-slats 7, each of which isprovided at its opposite ends with depending ears 8, which serve thetwofold function of restin against the top of the next lower slat anspacing it properly there: from and of also receiving a rivet orfastening device 9 for securing the slat in position. As shown in the.drawings, the storm-slats 7 preferably are more inclined thanthe top andbottom. of the member A, so that when said member is in osition theslatswill incline rearwardly and upwar ly.,

' Each of thestorm-slat-s 7 at itsforwar edge is formed with adependingstorm-flange 10, which is parallel with the laterally-extendingstor'm-flangesfi on the sides 5 of the member A. As shown inthedrawings, all the storm-flan es 2, 4, 6, and 10 are in the samevertical ane at the forward end of the 'member A; ach of the storm-slats7 at its rear end is provided with a forwardly and upwardly directedstorm-flange 11, which is disposed in a horizontal plane considerablyabove the lower edge of the de ending storm- -flan e 10 of the next hiher s at 7 In rear of t e-storm-slats 7 an about midwa is provided witha vertically-disposed upper screen-slat12 and a vertical y-disposedlower screen-slat 13, each of said slats be1n formed, preferably, withrearwardly-exten ing ears be tween itsfront and rear ends the mem er A14, which are riveted, soldered, or otherwise suitably secured tothesides 5. of the member A. Each of the screen-slats 12 and 13preferably consists of a strip of metal folded lon- ,gitudina'lly uponitself to form op ositely-extendingslots into which are fitte the upperand lower edges of a screen 15. By foldlng the screen-slats 12 and 13upon themselves inthe manner described the screen 15 is. heldsecurely-in place in a-strong, simple, and durable manner. erablyv israised slightly above. the bottom-3 of the member A to form a narrowslot16, which constitutes an esca e-opening in the event that any water sho(1 by any chance The lower screen-slat 13-pref- IIO when the member B isdrawn rearwardly in the member vA will contact with the verticalguard-flange 17, so as to limit the rearward movement of said member Band also act as a watershed whenever necessary to permit water to rundownward from the bottom of the inner member B onto the bottom of theouter member A in the event that water should ever penetrate .so farinto the ventilator. The rear end 22 of the member B is provided with acentrally-disposed rectanguar door-opening 23, which is adapted to beclosed by adoor 24, pivotally mounted upon a bar 25, extending along itsupper end and suitably connected with the sides 26 of the member B. Atits lower end the door-24 is provided with a forwardly-extendingbracing-flange 27, which when the door is opened is adapted to contactwith. the top 28 of'the member B and limit the upward movement of saiddoor. As shown in the drawings, the

door 24 is mounted entirely within the rear end of the member B, so thatit can only swing in a forward and'upward direction. On its rear facethe door 24 is provided with a pair of securing devices or eyes 29,'withwhich is detachably connected a springbracket comprising a pair ofdiverging arms '30, integrally connected at their rear ends by resilientcoils 31. By forcing the diverging arms .30 toward each other theirforward ends can be readily disengaged from the eyes 29. The upper arm30 of the spring-bracket preferably is so shaped as to be approximatelyparallel with the topof the member B. At their forward ends the arms 30are bent, as indicated at 32, to form broad bearing-shoes, which arefitted flat against the rear face of the door 24 and serve to preventthe bracket from: swinging laterally within the securing devices 29.Suitably secured .to the eyes formed by the spring-coils 31 is aflexible closing element or cord 33, which extends through a 'de memberor eye 34. at the central portion of-the upper end of the inner memberB, after which it extends through a similar'guide member 35 at one sideof said member'B. Also secured to the eyes or coils 31 is a flexibleopening element 36, which extends through a guide member 37 at the lowerend of the member B and then through the guide members 34 and 35. Bydrawin upon the closing member 33 the rear end 0 the spring-bracket,consisting of the arms 30 will be drawn upward, thus closing the door,

'ing stormand by loosenin the closing element 33 and drawing upon theopening element 36 the door. will be 0 ened and held in raised position.It will e understood that whenever desired the door 24 can be providedwith a suitable lock or latch 38 for securing it in closed osition. thatw enever it is desired to leave the ventilator permanently in closed oropened osition the springbracket, consisting o the arms 30, can bedetached from the door 24, together with the flexible elements 33 and36. Furthermore, the spring-bracket can be detached from the door forconvenience in shipping the ventilator.

By reason of the fact that the outer and inner parallelogrammaticmembers A and B are telescoped together the improved ventilator can beeasily and uickly adjusted to the thickness of any wal in which itisdesired to place the same. By reason of the peculiar shape of themembers A and B their top and bottom portions will incline upward fromtheir outer to their inner ends when they'are properly secured ina'wall, for which reason the penetration of water into a room throughthe ventilator will be impossible, and

' an upward current of fresh airwill be induced.

The improved device of this invention is strong, simple, durable, andinexpensive in construction, as well as thoroughly efficient inoperation.
